Application filed August 29, 1910. Serial No. 579,519.

To all whom it may concern: Be it known that I, HENRY KLEMAN, a

resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Smoke-Consumers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,

form of cooler, and Fig. 7 is a detailv sectional view on the line V'IIVII of Fig.- 1.

My invention relates to the class of smoke consumers wherein the particles of soot, dust and unconsumed products are mechanically separated from the hot air and gases, by forcing the smoke from the flue through a llqi lld bath.

he object of my invention is to provide cheap and simple apparatus m which the smoke is forced throu h a cooler to condense the gases, after w ich they are forced through a separator to remove all of the heavy matter, and after which they are again passed into the furnace with a suitable amount of oxygen so that the gases will be consumed. 1

which is contained in the can be collected and utilize for VENOUS hiya Another object of my invention is to collect all of the tar, and unconsumed matter, sea and which roducts. Still another object of my'invention is to utilize the" heat of the, ases to heat the water at thesame time t at the gases are cooling and condensing,- which'can be used for any desirable purpose The precise nature of my invention will be best understood by reference to the ac-1 companying drawings, which will now be described, it being premised, however, that various changes may be made in the details -'of construct1on and general. arrangement of the parts without departing from the spiritand scope of my invention, as defined in the appended claims. 4 I In the drawings, the numeral 2 represents a stack leading from a smoke box 3 of a boiler 4, having the usual fire box-or combustion chamber 5 and an ash pit 6.

6* are doors pivotally mounted in the ash pit, and connected to each is a lever 6".-

These levers are-connected to each other by a link. 6fis a hand lever connected to one ofsaid levers and is arranged to close both doors when the ash pit is to be cleaned.

7 is a pipeleading from the stack 2 to a fan 8.

9 is a gate valve in the pipe 7, and 10 is a butterfly valve in the'stack 2 above the connection between'the pipe 7 and the stack.

11 is a pipe leading-from the fan 8 to a coil of pipes 12 in a cooler 13.- In Fig. 1, I have illustrated the cooler 13 of cylindrical form, and contained in the central portion thereof is a separator chamber 14, containnected to the'cooling coil. 12 and a rectangular pipe 17 which is in communication 'with the separator 15. The agitator 15 is supported slightly above the bottom of the.

separating chamber 14, and the bottom of this agitator, is perforated'as indicated at 18.

19 1s a curved perforated shield or deflector, one end of. which is secured to the bottom of the agitator forthe purpose hereinafter described.

' 21, is a' return pipe from the separator chamber 14 to a receptacle 22 in the up er portion of the'ash .pit 6, which is provided with ,bafiies 23 for the purpose hereinafter ing an agitator 15, and 16 is a pipe coni 24 is a butterfly valve the ipe 21 and is adapted to be closed to cut 0 a portion of the gases, from the separator 14. 25fis a. Y connection in the pipe 21, two ends of which are connected to said pipe,

the third end extendingrearwardly, and to which is connected a nozzle 26. 27 is a slide onthis end of the .Y and is arranged -to. be moved back and forthcby means of the hand lever 28 to open and close "the opening 29. between the end of the Y and the nozzle 26.

3035' a small pipe leading 11 inte the rear end of the'nozzle 26, and .15.. provided with -a hand valve 31 to open and dose n cation between the nozzle and thepipe 1.

from the' pipe M pipe le 32 is an air pipe leading from a fan 33 to the nozzle 26 and in the rear of the end of the pipe 30. 8

34 is a water supply ipe and connected to this pipe 34 is a vave controlled inlet pipe 35 to the interior of the separator chamber 14. p

36 is a valve controlled inlet pipe from the pipe 34 to the interior of the cooler 13, and 37 is a valve controlled spray pipe leading from the pipe' 34 into the upper portion of the separator chamber 14, which is, arranged to spray the gases passing from the separator chamber 14 to the fire box.

38 is a valve controlled overflow from the cooler 13 which may extend to a pump arranged to supply water to the boiler 4, or to any other point where it is desired to utilize the heated water.

39 is an overflow pipe from the separator chamber 14 which is always open, and is of sufiicient area to maintain the level of the water slightly above the bottom of the agitator 15 as indicated in Fig. 1.

40 is a valve controlled pipe leading from the bottom of the. chamber 14 to the overflow. pipe 39, and is adapted to drain off the contents of the separator chamber 14 through the pipe 39, which maybe connected ta suitable tank in which the collected matter from the separator chamber may be retained, and which may afterward be collected and used for'the manufacture of various by-products.

41 1s a'water gage connected to the cooling chamber 14 to indicate the height of the water within said chamber.

42 is a screen in the pipe 7 and adjacent to the o eningto the fan 8, and 43 is a g from the pipe 7 to a container 44, which isarranged to receive cinders, etc., which will be deflected by means of the screen 42. p

is a gate valve in the bottom ofthe 45 container 44, and 46 is a butterfly valve in the'pipe 43 When it is desired to empty the container'44, thebutterfly valve 46 1s closed, and the valve 45 is opened and after the container 44 has been emptied, the valve 59 45 is closed and the butterfly valve 46 is opened to permit the cinders, etc., to fall into said container.

47 a steam gage connected to the upper ortion of the chamber 13 for indicatmy mg t e pressure within said chamber. '48 is a valve controlled flueleading from the ash pit to the fire box.

The operation is as follows: Fire is first started in the fire box 5, the valve 10 to the an stack 2 bein closed, and the gate valve 9 certain amount of air being opene 'The fan 8 bein started to draw air .from the ash pit, t e' door of which may be opened for a short time, a will be drawn from at the chamber 14. 33 is also in operwater and masses ation at this time which will force air through the nozzle 26 and pipe 21 to the box 22, which will be deflected by means of the bafies 23 across the bottom of the grate bars. The smoke passes through the pipes 7 and 11 and the cooling coils 12 to the agitator 15 through the medium of the pipes-16 and 17. The current of gas and smoke passing through the agitator 15 will vibrate the shield 19, some of it passing around the shield and some of it through the orifice therein, and then passing out through the water in the bottom of the agitator and the orificeslS to the receiving chamber, then through pipe 21 back to the fire box. The impact of the smoke and gas against the shoulder will depress the free end and partially submerge it in the water in the agitator, and the spring of the metal will return it against the current of the smoke the spring of the metal will constantly vibrate the shield which will separate the gas, thereby preventing the gas from passing through the separator in large globu es which wi l thoroughl wash the heavy matter from the gas. if "it is desued, the slide 27 can be moved back as indlcated in Fig. 1, and the valve 31 opened, WhlOh will permit some of the gas to escape through the nozzle 26, which will draw .air through the opening '29 and be properl mixed so as to supply suficient oxygen .wit

the gas during its passage to the fire box. If desired, the valve 31 and the opening 29 can lie clogied, in which case the fan 33 will supp y .su cient oxygen to the as 'assin through the pipe 21 to the fire b ox 1% fOIl perfect combustion. The gas in passing through the cooling coils 12 will be cooled down which will condense the gases, and

which will in turn heat'the water in the used as previously chamber 14 will be thoroughly washed,

which will remove all of the soot and other matter which will be deposited in the bottom of said chamber, and which can afterward be drawn olf to be used as heretofore described.

In Fig. 4,I have illustrated a steam drum 49, which is connected to the upper portion of the chamber 13, and throu h which steam mafl be drawn for any suitab e purpose.

Fig. 5, I have shown a modification in which I have used all of the same reference numerals with the letter a 'afiixed, and in which case, I have shown the receiving chamber and cooler separated from each other, with the fan placed between the cooler and the separating chamber. By using a The. gases while.

' drawn off memes construction of this character, the fan will be kept comparativel cool, as all of the gases, etc., will be coo ed before their passage through the fan. In Fig. 6, l have shown a further modification of a cooling chamber in whichl have shown a tank having an upper and lower chamber 50 and 51 connected by means of vertical pipes 52, through which the gases pass. In this case, the water for cooling the gases is contained in the chamber 53 between the heads.

The advantages of my invention result from the provision of means. for thoroughly cooling and washing the gases from the furnace, to which may be added the proper amount of oxygen, which is then passed to the furnace for re-consumption.

Another object of my invention is to provide means for collecting the heavy matter in the gases and which -can afterward be and utilized for manufacturing various by-products. Further in the pros vision of means forheating water by means of the hot gases which can be 'used as feed water for the boiler or for any other'purpipe to theair space below the grate, a fan I to draw the gas from the stack through the pipe an pose.
